DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Following, the top toy of the present invention is explained based on anembodiment shown in the drawings.

Overall Structure

FIG. 1 is a perspective view showing a top toy 1 of the presentembodiment, and FIG. 2 is a perspective view of the top toy 1 in adisassembled state.

This top toy 1 is a top toy that can be used in a so-called battle game.This top toy 1 can be used in a battle game in which winning occurs bydisassembling the other party's top toy 1 by the impact force ofcolliding with each other as shown in FIG. 2.

This top toy 1 is configured by a shaft part 10, a variable performancering 30, and a body 40.

Details 1. Shaft Part 10

FIG. 3 is an exploded perspective view showing half of the shaft part 10and the variable performance ring 30. The remaining half has asymmetrical shape.

The shaft part 10 comprises a rotation shaft 11 in the lower part, aflange 12 in the middle part, and a cylindrical part 13 in the upperpart. The rotation shaft 11, the flange 12, and the cylindrical part 13are formed using synthetic resin. Of course, the material is not limitedto a synthetic resin, and the entirety or a portion may also be formedusing metal or rubber, or another material.

The lower part of the flange 12 of the shaft part 10 has a shape that isconstricted in stages facing from the flange 12 toward the rotationshaft 11, and overall, forms substantially an inverted cone shape.

One hole 15 each is formed front and rear on the flange 12 and thecylindrical part 13. Also, on the flange 12 and the cylindrical part 13,one protruding part 16 each is formed at left and right of the flange12. These protruding parts 16 are positioned at top and bottom of theflange 12, and the outer surface is flush with the outer circumferencesurface of the flange 12.

Also, a cylindrical body 14 is erected on the inside of the cylindricalpart 13. The top end of this cylindrical body 14 is not particularlylimited, but is set at a position slightly higher than the top end ofthe cylindrical part 13. One each of a claw (first coupling element) 17protruding radially outward is formed front and rear on the top end partof this cylindrical body 14.

Also, the shaft part 10 comprises a cylindrical moving member 18 that isprovided on the inside of the cylindrical part 13 and that surrounds theupper outer circumference of the cylindrical body 14. One each of aprojecting piece 18 a that protrudes radially outward at front and rearis formed on the lower end part of this moving member 18. Eachprojecting piece 18 a is inserted in the hole 15. The moving member 18is able to move in the vertical direction. Also, the moving member 18 isenergized upward by a coil spring 19 that is wound around thecylindrical body 14, and normally, the projecting piece 18 a abuts thetop edge of the hole 15.

One each of a convex strip (resistance element) 20 is formed extendingin the radial direction at left and right on the top surface 18 b ofthis moving member 18.

2. Variable Performance Ring 30

With this embodiment, a flywheel made of metal is used as the variableperformance ring 30, for example. The variable performance ring 30 hassubstantially a plate shape. An annular step part 30 a that can housethe flange 12 of the shaft part 10 from below is formed on the bottomsurface of this variable performance ring 30. Also, one inverse U-shapedprotruding part 31 each protruding facing upward respectively in thelateral direction is formed on the top surface of this variableperformance ring 30. A concave part 32 that can house the protrudingpart 16 of the shaft part 10 from below is formed on the lower part ofeach protruding part 31. Meanwhile, a tongue piece 33 (an example of theprojection) protruding upward just outside of each protruding part 31 isformed on the top surface of the variable performance ring 30.

As this variable performance ring 30, instead of the flywheel, or beingintegrally formed with the flywheel, this can be an item that has aprotruding part on the outer circumference surface and makes it easy toattack the top toy 1 of the other party, or an item that has a concavepart on the outer circumference surface and is less susceptible toattacks from the top toy 1 of the other party.

3. Body 40

FIG. 4 is a perspective view of the body 40 seen from below, FIG. 5 isan exploded perspective view of the body 40, and FIGS. 6A and 6B areplan views for explaining the action of the top toy.

The body 40 comprises a trunk main body 40 a, a weight 40 b, and a tip40 c, and the body 40 is configured by assembling these.

The trunk main body 40 a comprises a ceiling wall 42, and is formed in adisk shape. At the bottom end surface of an annular wall 43 of theinside of the trunk main body 40 a, claws 44 extending radially inwardare provided projecting at two symmetrical positions. Also, at thebottom end surface of the projection of the tip 40 c, a corrugated part(resistance element) 45 for which unevenness is continuously formedextending in the radial direction is formed at two symmetricalpositions, and this corrugated part 45 meshes with the convex strip(resistance element) 20 of the shaft part 10.

Also, arc shaped slits 46 for which the tongue piece 33 of the variableperformance ring 30 can be inserted from below are respectively formedat two symmetrical positions on the trunk main body 40 a. Thecircumference direction length of each arc shaped slit 46 is a length bywhich the tongue piece 33 can move sufficiently.

A blade 47 is arranged along the entire circumference on the outercircumference of the trunk main body 40 a. With the top toy 1 of theembodiment, as the blade 47, an upper blade 48 and a lower blade 49 arecomprised.

Of these, the upper blade 48 is a series of fixed blades having acorrugated form for the external form. Meanwhile, as shown in FIGS. 6Aand 6B, the lower blade 49 is configured from two fixed blades 49 ahaving a corrugated form for the external form respectively formed attwo symmetrical positions, and two rotating blades 51 having acorrugated form for the external form respectively arranged at twosymmetrical positions, and has a form for which the fixed blades 49 aand the rotating blades 51 are arranged alternately in the circumferencedirection.

The rotating blades 51 are configured to be able to rotate with shafts50, that are provided at the outer circumference part of the body 40,and that are parallel to the axis center, at the center. The shafts 50support the rotating blades 51 at the rotation direction rear part sideof the top toy 1. With the shaft 50 as a reference, following we willexplain the front side part of the rotation direction of the top toy 1as the tip side part of the rotating blade 51, and the rear side part ofthe rotation direction as the base end side part of the rotating blade51.

A corrugated part (blade function part) 51 a is formed on the outside ofthe part near the shaft 50 of the tip side part of the rotating blade51. Also, a sliding part 51 b that advances and retreats with respect tothe arc shaped slit 46 by rotating is formed on the inner edge of therotating blade 51. The edge of the inside of the sliding part 51 b isindented in a bow shape.

The tip end side part of this rotating blade 51, when retreated from thearc shaped slit 46, sticks out further radially outward than the maximumdiameter part of the upper blade 48 and the fixed blade 49 a (FIG. 6A).When the sliding part 51 b is advanced fully in the arc shaped slit 46,the tip end side part of this rotating blade 51 is retracted furtherradially inward than the maximum diameter part of the upper blade 48 andthe fixed blade 49 a (FIG. 6B). This position is taken when the tonguepiece 33 is at the counterclockwise side end part of the arc shaped slit46. At this time, the tongue piece 33 touches the end of the base endside part of the rotating blade 51, and with the tip end side part ofthe rotating blade 51, the sliding part 51 b fully advances in the arcshaped slit 46 b.

From this state, when the body 40 and the shaft part 10 perform relativerotation in the direction that releases coupling, the tongue piece 33moves facing the clockwise side end part of the arc shaped slit 46 b.Also, while in sliding contact with the sliding part 51 b, the tonguepiece 33 pushes the tip end side part of the rotating blade 51 furtherradially outward than the maximum diameter part of the fixed blade 49 a.This state is shown in FIG. 6A.

4. Assembly Method for Top Toy 1

First, the protruding part 16 of the shaft part 10 is matched with theconcave part 32 of the variable performance ring 30 from below, and theshaft part 10 and the variable performance ring 30 are assembled in afitted state. Next, this assembled body approaches the body 40 frombelow. At this time, the tongue piece 33 of the variable performancering 30 of the assembled body is matched to the end part 46 b of theclockwise side of the arc shaped slit 46 of the body 40. This state is astate in which the claw 17 of the shaft part 10 and the claw 44 of thebody 40 do not overlap in the vertical direction, specifically, the claw17 of the shaft part is positioned between the claws 44 of the body 40.This state is the coupling release state. After that, the shaft part 10of the assembled body is pressed to the body 40 side. Having done that,first, the variable performance ring 30 is pressed against the bottomsurface of the body 40. Furthermore, the coil spring 19 inside the shaftpart 10 flexes, and the claw 17 of the shaft part 10 is pushed uprelatively upward compared to the claw 44 of the body 40. Also, theshaft part 10 is rotated integrally with the variable performance ring30 with respect to the body 40 until the tongue piece 33 reaches an endpart 46 a of the opposite side to the abovementioned end part 46 b.Having done that, the claw 17 of the shaft part 10 and the claw 44 ofthe body 40 are in a state overlapping vertically. In this state, whenthe hand lets go of the shaft part 10, by the energizing force of thespring 19 within the shaft part 10, the bottom surface of the claw 17 ofthe shaft part 10 and the top surface of the claw 44 of the body 40abut. This state, specifically, the state in which the bottom surface ofthe claw 17 of the body 40 and the top surface of the claw 44 of thebody 40 abut, is the coupled state. By doing this, the shaft part 10,the variable performance ring 30, and the body 40 are coupled, and thetop toy 1 like that shown in FIG. 1 is assembled.

5. How to Play

Following, an example of how to play using this top toy 1 is explained.

The charge of the rotational force of the top toy 1 is performed by alauncher 60 such as that shown in FIG. 7. The top toy 1 is mounted inthis launcher 60. Specifically, a fork 63 is inserted in the arc shapedslit 46 of the body 40. Then, a projection 63 b is engaged with the edgeof the end part of the rotation direction side of the arc shaped slit 46of the body 40. By doing this, the top toy 1 is mounted in the launcher60.

This launcher 60 comprises a disk (not illustrated) inside, and theconfiguration is such that this disk is energized in one rotationdirection by a spiral spring (not illustrated), and also, when a cord(not illustrated) wound around the disk is pulled using a handle 61, thedisk rotates, and a top holder 62 rotates. The rotation of this topholder 62 is transmitted to the top toy 1 by the fork 63 providedprotruding downward, and the top toy 1 is rotated in one rotationdirection. To rotate the top toy 1 in the other rotation direction withthe launcher 60, the internal gear of the launcher 60 is switched, oranother launcher 60 is used.

Then, when the handle 61 of the launcher 60 is pulled all the way, whilethe rotation of the disk and thus the top holder 62 is stopped, the toptoy 1 still rotates by inertia, so it follows an inclined surface 63 aof the fork 63 and the top toy 1 separates from the top holder 62.

With an example of this play method, the top toy 1 released into thefield is rotated in the clockwise direction. In the initial state, thecorrugated part 51 a of the rotating blade 51 is positioned by thetongue piece 33 further radially inward than a maximum diameter part(shown by the double dot-dash line) A of the upper blade 48 and thefixed blade 49 a as shown in FIG. 6B. Then, when the upper blade 48 andthe fixed blade 49 collide with the other party top toy 1 in aprescribed field, due to impact force or rubbing, etc., due to thecollision, a force in the direction opposite to the rotation force ofthe shaft part 10 and the variable performance ring 30 acts on the body40, and the body 40 rotates relatively in the direction opposite to therotation direction of the shaft part 10 and the variable performancering 30.

However, the convex strip 20 meshes with the corrugated part 45 of thebottom surface of the body 40, and the energizing force of the spring 19within the shaft part 10 acts on the convex strip 20, so with eachacting of the impact force due to collision, the shaft part 10 rotatesrelatively to the body 40, changing the meshing position. Then, at thecoupling release position, specifically, when the tongue piece 33reaches the end part 46 a of the clockwise direction side of the arcshaped slit 46, the claw 44 of the body 40 separates from the claw 17 ofthe shaft part 10, so the body 40 breaks away from the shaft part 10 bythe energization force of the spring 19 within the shaft part 10. Then,the top toy 1 is disassembled as shown in FIG. 2.

With this top toy 1, the corrugated part 51 b of the rotating blade 51gradually moves further radially outward than the maximum diameter partA following movement of the tongue piece 33 in the coupling releasedirection within the arc shaped slit 46. Then, when the top toy 1 of theother party collides with the rotating blade 51 in the state shown inFIG. 6A, the rotating blade 51 is rotated in the clockwise directionwith the shaft 50 as the center as shown in FIG. 6B, and the tonguepiece 33 and thus the shaft part 10 rotate relative to the body 40 inthe direction that returns to the start.

By doing this, it is possible to delay disassembly of the body 40 andthe shaft part 10.

Above, an embodiment of the present invention was explained, but thepresent invention is not limited to this embodiment, and it goes withoutsaying that various modifications are possible within a range that doesnot stray from the gist of the invention.

For example, with the abovementioned embodiment, we explained a case ofdoing relative rotation in the direction by which the shaft part 10 andthe body 40 return to the start when the body 40 receives an externalimpact, but it is also possible to, when the tongue piece 33 moves inthe coupling release direction, have the corrugated part 51 a of therotating blade 51 move radially inward by being in sliding contact withthat tongue piece 33. This can be easily understood if consideringmoving of the tongue piece 33 in the direction of the end part 46 b ofthe counterclockwise direction side from the end part 46 a of theclockwise direction side in FIGS. 6A and 6B. Working in this way, as thetongue piece 33 approaches the coupling release direction, the entireblade 49 approaches a perfect circle, so the defense power graduallyincreases.

Also, with the abovementioned embodiment, both end parts of the rotatingblade 51 are configured to advance into the inside of the arc shapedslit 46 alternately according to the rotation direction of the rotatingblade 51, but it is also possible to have a structure with which thesliding part 51 b of the rotating blade 51 can advance and retreat atleast in the movement direction of the tongue piece 33.

Also, with the abovementioned embodiment, the outer circumference shapewas changed following the movement of the tongue piece 33, but when thecentrifugal force at rotation start is large, the corrugated part 51 aof the rotating blade 51 is operated radially outward by centrifugalforce, and when the centrifugal force weakens and the sliding part 51 bof the rotating member 51 advances inside the arc shaped slit 46, bybeing in sliding contact with the tongue piece 33, the rotating blade 51is rotated, and it is possible to operate the corrugated part 51 aradially outward.

Also, with the abovementioned embodiment, a spring that energizes therotating blade 51 is not provided, but it is also possible to provide aspring that energizes in the direction for which the sliding part 51 bof the rotating blade 51 advances in the movement direction of thetongue piece 33.

Effect of the Invention

The rotating blade rotates by movement of a projection within an arcshaped slit, so it is possible to reliably change the external form of ablade of a top toy.

With the rotating blade, when the projection moves within the arc shapedslit in the direction in which coupling is released, a blade functionpart operates radially outward, and when an external impact is appliedto the rotating blade, the projection is pushed back relativelyintegrally with the shaft part, so it is possible to delay disassemblyof the body and the shaft part.

With the rotating blade, when the projection is moved within the arcshaped slit in the direction in which coupling is released, the bladefunction part operates radially inward, so the rotating blade is housed,becoming a shape closer to a perfect circle, making is possible torealize a top toy for which defense power is increased as it goes to thelatter half of a match.
